Wing:
Begin the construction of the wing by cutting the carbon strip 3x0.5 mm into three roughly equal parts -
approx. 330 mm. One piece for the wing center section and one each for the left and right side of the
wing. The carbon strips are only cut from the top into the wing parts.
Prepare a groove in the top of the wing center section 50mm from the leading edge of the wing for the
carbon strip with a sharp knife. Approximately 30 mm from both sides, the grove must be slightly
deeper, so that a second carbon strip has enough space from the outer wings in the correct dihedral.
Press the carbon strip into the center wing section on a flat surface, the strip should protrude on both
sides in the same length.
Lay the outer wings to the center wing section and make the cuts for their carbon strips according to
the position of the carbon strip in the center wing section. The carbon strips in the outer wings may be
in front of or behind the center wing carbon strip, and later the overlapping ends are glued together
from the sides. The grooves in the outer wings must be slightly deeper on the side where they are
glued to the center wing section, so that the carbon strip of the center wing section in the outer wings
also has enough space in the correct dihedral.
Glue the carbon strips into all wing parts with thin CA, but do not glue them in the places where the
strips will overlap (about 30 mm from the edges).
Note:
If you also want to retrofit the flaps, the wing trailing edge should not be glued
in the depth of about 35 mm, or better, cut off the flaps before gluing the wing
parts together. Read the instructions further.
Try to put the wing pieces together, the correct dihedral is 40mm at both wing tips.
If everything fits
and you do not need to make the cuts for the carbon strips deeper, you can glue the wing parts
together, again, ideally with the PU glue in the core as described above and thin CA on the
circumference.
It is helpful to first glue the wing on the underside with the CA + activator, then adjust
the correct dihedral (40mm at the wing tips) and then glue the overlapping carbon strips with low-
viscosity CA first (+ lightly spray with activator) together in their full length.
For the glue to be better able to tile in, you can slightly open the carbon strips with pins when gluing.
Then glue the circumference of the area with CA from above.
